Get one of those converters that plugs into your cigarette lighter and it has outlets on it. They sell them at radio shack and probably walmart. Not sure what they are called.... 12volt Converters I guess?!
You can go on amazon.com and type in "universal laptop adapter" and you should be able to find a charger that will fit in your car. I found one for my compaq for about $7.
just buy the plug in that gives you an outlet. They sell them at radioshack. It is just a little thing you plug in that gives you a 3-prong fitting outlet that you can plug your laptop into. That is what i do.
